Predjama Castle

Nine kilometres northwest of Postojna caves, but not served by public transport, is the precariously sited Predjama Castle. Built into and around an elevated cave entrance in the midst of the dramatic karst landscape, this sixteenth-century fortress is a striking sight and affords excellent views of the surrounding countryside. Its damp, sparsely filled interior is less rewarding, though you can see weaponry and artefacts dating back to its heyday as the castle of the legendary knight Erazem Lueger. The easiest way to get here is to rent bikes from the Hotel Sport at Kolodvorska 1 in Postojna.
